creda 37754 no heat and its not the stats

[admin]

Hi helpful people!
My creda 37754 condenser dryer recently suffered a broken belt. Being a bit broke and also an electronic systems engineer I decided to replace it myself. when I put it all back together I had no start, found a connection that had pulled off as the frame flexed. Dryer starts but no heat.
Checked both heater stats ok, and the front one at the top of the drum also ok.
Realised that water tank microswitch was disconnected (I had de-gunged the float during dis-assembly) only slight problem without a schematic I wasn’t quite sure which way the 3 connections were configured: Thin black wire to front panel Empty Water neon, blue+blue&white pair which seem to be Neutral from mains, blue+dark blue which seem to be the switched supply to the heater box. Using a meter on the micro switch shows Pin 1 is switched either to Pin 2 or Pin 4, with the tank empty position meaning Pin 1 to Pin 2 is the active path, and Pin 1 is switched to Pin 4 when the tank needs emptying.

What’s the right configuration here? I seem to have tried 3 configurations without success so far 😳 (no start for the config that effectively gives no Neutral path, or Neon lit whenever mains on, extinguishing once tumble dryer is started but no heat. In this latter configuration the Neon lights when microswitch activated to simulate tank full condition)

Grateful for any advice anyone is prepared to offer?
